Tata Indicom Data Card on Ubuntu

Got my Tata Indicom data (which is basically a Huawei E321) card to work my laptop running Ubuntu Edgy. It was fairly straightforward process, with ubuntu automatically doing most of the work. :)

1. After inserting the card, the modem got detected at /dev/ttyUSB0.
2. Ran

sudo wvdialconf
and it setup the default configuration
3. The I edited the /etc/wvdial.conf file to setup the Phone number, Username and password.
Phone = #777
Password = internet
Username = internet
4. Now run sudo wvdial R and that's it. After a series of debug messages, you should be connected to the internet.

Now I still need to figure how to get the signal strength of the network Iam in.

I have installed UBUNTU and want to use my TATA indicom dial up phone for internet it is LG350 with USB connection
I have tried the code
[dialer Defaults]
Modem = /dev/ttyS0
Modem type = Analog Modem
Stupid Mode=1
Then I created the
resol.conf as
name server
followed by a sudo wvdial
I am using a LG350 phone which I am connecting to a USB port and not serial port
I am getting the error
/dev/ttyS0 input/output error
it is because the tty should be something else for USB please let me know.

Thank you so much. It really worked. I had been struggling with my modem for the past many months, and finally your post came to my aid. Thanks a lot. :)
